Inc. recently published an article about the "ethical hacker" that you just might want to do business with. This is the person who can "evaluate your company's security vulnerabilities" and help you to fix them before it's too late. They have some interesting tactics, including deliberately dropping a USB drive in the office to see what your employees do with it. Will they, out of curiosity, stick it in their computer? And what if it was infected with a huge virus? The ethical hacker will also look at company information online, including employee social networking profiles, to make sure there aren't any information leaks.
